Hereinafter, the smart instrumentation device 100 according to an embodiment of the present invention will be described in detail with reference to the attached drawings.

Figure 1 is a diagram illustrating the use of a smart instrumentation device 100 according to an embodiment of the present invention.

Referring to FIG. 1, the smart instrumentation device 100 according to an embodiment of the present invention is installed in the distribution board 10 that distributes power to home appliances, etc., and can monitor power status, etc. In general, in order to determine the safety status of the distribution panel 10, a safety inspector must visit and inspect it in person, which has the problem of requiring a lot of manpower and time.

However, the smart instrumentation device 100 according to an embodiment of the present invention allows even general users without specialized knowledge to determine the safety status of the distribution board 10, and as described later, the current power usage is in a safe state or a dangerous state. You can intuit it.

Additionally, if the distribution board 10 is determined to be in a dangerous state, a warning message can be output to the user to take follow-up measures, such as calling professional personnel or calling 119.

Figure 2 is a block diagram of a smart instrumentation device 100 according to an embodiment of the present invention.

Referring to Figure 2, the smart instrumentation device 100 according to an embodiment of the present invention includes a power measurement unit 101, a safety inspection unit 103, an output unit 105, and a communication unit 107. 10) You can check the power status.

In more detail, the power measurement unit 101 according to an embodiment of the present invention can measure the instantaneous power of the distribution board 10. At this time, the reason for measuring the instantaneous power is that if the distribution board 10 may momentarily fall into an overload, the instantaneous power or instantaneous power must be measured in order to determine this. At this time, instantaneous power or instantaneous power refers to power at a specific point in time, which is distinct from average power and complex power.

In addition, the safety inspection unit 103 according to an embodiment of the present invention generates safety status information including information on whether the distribution board 10 has a short circuit, discharge, arc, overheat, and overcurrent. You can.

At this time, the safety check unit 103 is a power analyzer that determines whether there is a short circuit, discharge, and overcurrent of the distribution panel 10, and analyzes the resistance component, inductive component, and capacitance component corresponding to the distribution panel 10. It may include an arc analyzer that detects whether an effective arc has occurred and uses this to determine whether the arc has occurred, and a temperature detector that detects the temperature of the distribution panel 10 to determine whether it is overheated.

At this time, the arc analyzer includes a load circuit for analyzing the load component of the distribution panel 10, and analyzes the resistance component (R), inductive component (L), and capacitive component (C) of the load to determine whether an effective arc occurs. It can be detected and used to determine whether the arc has occurred.

At this time, the arc can be divided into active arc, which causes electrical defects such as fire or deterioration, and ineffective arc, which is unrelated to electrical defects. The resistive, inductive, and capacitive components of the load are analyzed and synchronized, and the ineffective arc is removed. Only the occurrence of a valid arc can be detected.

In addition, to determine the effective arc, a special high-frequency sensor for detecting the arc frequency can be used, an R-L-C resonance circuit can be used, a voltage and current arc pulse synchronization circuit can be used, a low-frequency filter circuit can be used, or an oscillation frequency generation combination circuit can be used.

Furthermore, the form of the arc can be detected in the form of a micro electric spark or a complex parallel arc. A complex parallel arc is an arc that can occur before the wire is completely short-circuited, and the arc intensity can also be detected by dividing it into strong, weak, etc. .

In addition, the arc analyzer extracts the resonant frequency of the distribution bar, adjusts the frequency inside the arc analyzer to match the resonant frequency, detects whether an effective arc occurs, and uses this to determine whether the arc occurs. It may be possible.

At this time, by matching the resonant frequency of the distribution board 10 and the frequency inside the arc analyzer, detection of invalid arcs can be reduced and only effective arcs can be detected.

Additionally, the output unit 105 according to an embodiment of the present invention can visually output information about the instantaneous power and the safety status information. More details will be described later with reference to FIGS. 3 and 4 .

Additionally, the communication unit 107 according to an embodiment of the present invention can transmit the information on the instantaneous power and the safety status information to the management server 300.

At this time, the communication unit 107 can transmit and receive various data, signals, and information with the management server 300 and/or other smart instrumentation devices 100, as described later. In addition, the communication unit 107 may include a wireless communication module (e.g., a cellular communication module, a short-range wireless communication module, or a global navigation satellite system (GNSS) communication module) or a wired communication module (e.g., a local area network (LAN) communication module, or power line communication module). In addition, the communication unit 107 may use a first communication means (e.g., a cellular network, the Internet, or a long-distance communication network such as a computer network (e.g., LAN or WAN)) or a second communication means (e.g., Bluetooth, WiFi direct, or IrDA (e.g., It is possible to communicate with an external electronic device (management server 300 or another smart instrumentation device 100) through a short-range communication network (such as Infrared Data Association). These various types of communication modules may be integrated into one component (e.g., a single chip) or may be implemented as a plurality of separate components (e.g., multiple chips). Additionally, the communication unit 107 may operate based on communication standard technology.

Additionally, the communication unit 107 can reduce the amount of information by modifying the information transmitted and received with the management server 300 or other smart instrumentation devices 100 to use relatively less power. Preferably, the information can be modified using either RLE (Run-length encoding) or a lightweight hash function.

When repeated types of data are accumulated and transmitted, the RLE can be implemented to reduce the transmission size of the information while ensuring non-determinism of the information by reflecting the frequency, etc., in the information.

Additionally, a lightweight hash function is also one of the desirable implementation methods that can transform information to increase security while simultaneously saving too much computing power.

Figure 3 is an exemplary diagram showing the output unit 105 of the smart instrumentation device 100 according to an embodiment of the present invention.

Referring to FIG. 3, the output unit 105 includes a first LED (105-1) that visually outputs information about the instantaneous power and a second LED (105-2) that visually outputs the safety status information. It can be included.

At this time, the first LED 105-1 is formed of a plurality of first LED modules lined up, and operates by determining the number of the plurality of first LED modules to be operated based on the information about the instantaneous power. This can be done, and will be described in more detail later with reference to FIG. 4.

At this time, the second LED 105-2 may include a plurality of second LED modules with different colors depending on whether there is a short circuit, discharge, arc, overheat, or overcurrent.

At this time, the second LED module is composed of a plurality of modules and may operate in different colors based on safety conditions such as electrical leakage, discharge, arc, overheating, and overcurrent. For example, in a safe state, all of the second LED modules may emit blue light, but if a dangerous situation occurs due to short circuit or discharge, the second LED module corresponding to the short circuit or discharge may be configured to emit red light.

Figure 4 is a diagram showing the operation of the first LED 105-1 according to an embodiment of the present invention.

Referring to FIG. 4, the first LED 105-1 according to an embodiment of the present invention is formed by a plurality of first LED modules lined up, and the number of first LED modules is increased in proportion to the instantaneous power. It can be configured to operate in increasing order.

At this time, the first LED 105-1 may operate to correspond to the critical power 220 corresponding to the dangerous state and 80% of the total number of the first LED modules.

For example, each time the instantaneous power increases, the first LED module is controlled to operate additionally one by one, but the instantaneous power of the last 20% of the total number of the first LED modules exceeds the threshold power (220). It can be configured to operate only.

At this time, if the instantaneous power is below the threshold power 220, it can be set to the safety range 210.

This is because it is somewhat difficult to understand what instantaneous power means from the perspective of a general user, and it is impossible to intuit whether it is a dangerous or safe state just by looking at the instantaneous power value. It is composed.

At this time, the critical power 220 is an artificial intelligence module that generates a machine learning model that outputs the critical power 220 by inputting information about the instantaneous power and the safety status information in the management server 300. It can be output through .

At this time, the artificial intelligence module can perform learning to derive an accurate correlation using deep learning, a field of machine learning.

Additionally, the artificial intelligence module can calculate the weights of a plurality of inputs in the function through deep learning. In addition, various models such as RNN (Recurrent Neural Network), DNN (Deep Neural Network), and DRNN (Dynamic Recurrent Neural Network) can be used as artificial intelligence network models for such learning.

Here, RNN is a deep learning technique that simultaneously considers current and past data, and recurrent neural network (RNN) represents a neural network in which the connections between units that make up the artificial neural network form a directed cycle. Furthermore, various methods can be used to construct a recurrent neural network (RNN), such as Fully Recurrent Network, Hopfield Network, Elman Network, and ESN (Echo State network), LSTM (Long short term memory network), Bi-directional RNN, CTRNN (Continuous-time RNN), hierarchical RNN, quadratic RNN, etc. are representative examples. Additionally, as a method for learning a recurrent neural network (RNN), methods such as gradient descent, Hessian Free Optimization, and Global Optimization Method can be used.

In addition, as an artificial intelligence network model, a machine learning model can be created using the SVM (Supported Vector Machine) neural network algorithm, which is widely used in pattern recognition.

Here, SVM, or support vector machine, is one of the fields of machine learning and is a supervised learning model for pattern recognition and data analysis. It can be mainly used for classification and regression analysis, and a set of data belonging to one of the two categories is given. When lost, the SVM algorithm can create a non-probabilistic binary linear classification model that determines which category the new data belongs to based on the given data set.

In addition, the second LED 105-2 may include a plurality of second LED modules with different colors depending on whether there is a short circuit, discharge, arc generation, overheating, or overcurrent.

At this time, the first LED (105-1) operates by increasing the number of the first LED modules in proportion to the instantaneous power, and the critical power (220) corresponding to the dangerous state and the It can be operated to correspond to 80% of the total number.

At this time, the critical power 220 is an artificial intelligence module that generates a machine learning model that outputs the critical power 220 by inputting information about the instantaneous power and the safety status information in the management server 300. It can be output through .

It may include a management server 300.

At this time, since the configuration of the plurality of smart instrumentation devices 100 is the same as the configuration of the smart instrumentation device 100 described above, description is omitted.

At this time, the plurality of smart instrumentation devices 100 communicate with other adjacent smart instrumentation devices 100 through a second communication means, and when the communication speed of the first communication means is below the preset threshold communication speed. , the first safety state information is transmitted to another adjacent smart instrumentation device 100 through the second communication means, and the other adjacent smart instrumentation device 100 transmits the received first safety state information to the first communication means.

This means that although the management server 300 must receive safety status information through the smart instrumentation device 100, if a problem occurs in the first communication means, the safety status information is transmitted to the management server 300 even through the second communication means. This is to prevent gaps in safety inspection.
